The Measurement And Spatial Differentiation Of Supply-Demand Match For Residents' Well-being In Poy Ang Lake Area

According to the report of the 19th session of national congress of the communist party of China,the principal contradiction in Chinese society has been transformed into one between unbalanced and inadequate development and the people's growing needs for a better life.Well-being indicators are a better gauge of development than economic indicators.From this aspect,the main contradiction of our society in the new era reflects the matching relationship between the supply and demand of well-being.From the regional economics,analyzing the spatial relationship between the supply and demand of well-being is of great importance to promote regional coordinated development and comprehensively build a well-off society.This paper combines comprehensive evaluation model,GeoDetector model,Gini coefficient,Theil coefficient and other methods to measure the supply and demand level of residents' well-being and analyze the supply-demand matching mechanism and its spatial distribution and differentiation feature on county scale in Poyang lake area from 2007 to 2017.The main research conclusions are as follows:(1)The total supply level of residents' well-being in Poyang lake area increasedsignificantly from 2007 to 2017,while the total demand level declined significantly.This shows that the economic development and supply capacity of residents,well-being in Poyang lake area have been continuously promoted,and the living standard of residents and the development level of the region have been improved as well.In terms of the supply level of residents' well-being,the supply level within the socioeconomic system in Poyang lake area has increased significantly,while the supply level within the natural ecosystem has slowly declined.It indicates that the supply capacity of the natural ecosystem has been weakened in the process of economic and social development in Poyang lake area.(2)The sub-supplies of well-being within the socioeconomic system and the natural ecosystem of Poyang lake area are all the impact factors of residents'well-being demand,and the influence of the former is obviously stronger than that of the latter.The influence of infrastructure supply and medical supply are strong.The influence of impact factors for residents' well-being demand are different in various regions of Poyang lake area.Medical supply,education supply,social insurance and employment supply have greater impacts in the peripheral area around the lake,while the rest of sub-supplies have greater impacts in the lakeside area.(3)It is obvious that there exists spatial mismatch between the supply and demand of residents' well-being in the counties of Poyang lake area.The spatial supply-demand mismatch of residents' well-being is significantly intensified from 2016 to 2017.The spatial distribution of the high-high cluster area is stable,which is continuously located in the west of Poyang lake area.However,the spatial distribution of the low-low cluster area changes significantly over time,moving to the southeast of Poyang lake area,and reducing its scope as well.(4)The spatial differentiation of the supply-demand matching degree of residents' well-being in Poyang lake area widens from 2007 to 2017.This differentiation mainly comes from inter-county difference,and its overall contribution rate is up to 98 percent.However,the difference between the lakeside area and the peripheral area around the lake is much smaller,and its overall contribution rate is less than 2 percent.
